In recalculation of a model resistance into a real object resistance, one of difficult to estimate values is the shape coefficient. There are well known and tested methods of determining the (1+ko) coefficient for sea-going ships. In the case of inland vessels navigating in the limited depth waterways the problem has not been solved completely. The paper presents results of computations of the inland vessel shape coefficient determined by means of numerical methods (MOS). The shape coefficient has been calculated as a function of the block coefficient and block coefficient of the forebody of a barge hull. The calculations were based on five typical shapes of the transport inland vessels and were carried out for different depth to draught (h/T) ratios and different sailing speeds.
